REMOVAL & INSTALLATION
See Figure 1
The ignition module, referred to as either the Spark Control Computer (SCC) or Power Module by Chrysler, is mounted on the inner, left-hand fender, next to the battery. The SCC or Power Module is what develops into Chrysler's Powertrain Control Module (PCM).
- To gain access to the SCC, remove the battery from the vehicle.
- Disconnect the air inlet hose from the rear end of the SCC. Position the hose aside without disconnecting it from the air cleaner assembly.
- Detach the 10-way and the 14-way engine wiring harness connectors from the SCC.
Do not remove the grease from the 10-way dual connector or connector cavity in the SCC-this grease is used to prevent moisture from corroding the connector terminals.
- If the SCC is equipped with a vacuum transducer (carbureted engines), label and disconnect the vacuum hose from the SCC.
- Remove the SCC mounting screws and pull the SCC away from the inner fender. Remove the SCC from the vehicle.
- Hold the SCC in position against the inner fender, then install the mounting screws until snug.
- If equipped, attach the vacuum hose to the vacuum transducer.
- Inspect the amount of grease in the 10-way and 14-way connectors. If there is not at least 1 / 8 in. (3mm) of grease on the bottom of the SCC connector, apply Mopar® Multi-purpose grease Part No. 4318063, or equivalent, over the entire end of the connector plugs before reattaching them.
- Push the 14-way and 10-way connectors into their respective ports until the connector tangs engage fully. Give a slight tug backward to ensure that the connector plugs are fully engaged.
- Slide the air inlet hose over the SCC neck and tighten the clamp until snug.
- Install the battery and connect the battery cables.
